RISO INKS
Riso printing uses soy or rice oil based inks. The printing process doesn’t involve heating, therefore uses very little energy and all papers can be reused in test-printing, making the production low waste and environmentally friendly.
RISO offers a palette of 21 standard colours and 50 custom colours, including fluorescent and metallic inks - unlike any others.
Due to the natural ingredients of the inks, they have a few special characteristics:
-The ink sits on the paper, never dries completely...
-Can be smudged. Look out for dirty fingers!
-The coverage may be uneven and different from print to print.
The colours are semi-transparent and can be easily overprinted, resulting in new shades.Feel free to experiment!
Remember that for each colour, the paper goes into the machine, so it’s best to choose 4 colours max and play around with the overlapping.
